Donnell was featured in The Star’s annual Food Issue in March. He started out at a Lawrence coffeeshop on a lark and grew quickly from a weekend pop-up to renting a space above John Brown’s Underground. He took a hiatus this spring as he tried to decide if he was going to go back to pop-ups, rent a new space or start a food truck.

For now, Donnell’s sticking with pop-up events: “I’ve been experimenting with new flavors and refining them, and I’ve been meeting a lot of new people. There are a lot of folks in Kansas City who want to do the collaborative thing and Lawrence is not over it either.”

Earlier this month The Waffle Iron popped up at Port Fonda in Lawrence and The Filling Station in Kansas City. Donnell will be making more waffles in Kansas City starting Saturday.
